Product Description:

The EL6690 EtherCAT Terminal is a communication terminal for Ethernet-based networks. It is designed to synchronize distributed systems. The product is developed and designed by Beckhoff for effective operations in industrial automation systems.

The EL6690 EtherCAT terminal supports dual 100 Mbit/s Ethernet ports. These ports use standard RJ45 connectors for signal transmission. The secondary side features EtherCAT in and out interfaces. It allows seamless data exchange between two EtherCAT systems. The terminal supports cable lengths up to 100 meters. It operates using 100BASE-TX on the secondary connection and it ensures distributed clock synchronization across EtherCAT networks. This guarantees time-aligned data processing between connected devices. The EL EtherCAT terminal offers electrical isolation rated at 500 volts. This protects the E-bus side from secondary Ethernet disturbances. The E-bus current consumption is rated at 120 milliamps. The external current draw is 60 milliamps at 24 volts. The Beckhoff EL EtherCAT terminal supports reliable multi-device integration in complex settings. Its architecture is designed for efficient real-time communication. The terminal is suitable for modular machine designs and it supports high-speed synchronization of remote I/O systems. Its compact design allows DIN-rail installation in control cabinets. The unit plays a key role in multi-network synchronization.

The EL6690 EtherCAT terminal provides Ethernet bridging and clock control. It is often used in hybrid EtherCAT topologies. The terminal includes status LEDs for hardware diagnostics. These indicators provide instant feedback on operational conditions. The power supply on the primary side is through the E-bus. The secondary side receives power via a dedicated connector. This dual-supply design supports independent side operations. Its synchronization function enhances system timing accuracy. The unit is ideal for applications that requires cross-network communication.
